Call it nostalgia, but I missed the taste of animal crackers like they tasted when I was a boy. Sure, they still sell animal crackers in those retangular little boxes, but they don't taste like I remember.
I can't help you with the animal shape, but if you want that great animal cracker taste, just like the good old days, try Traditional Marias Cookies by Gamesa. These cookies are made in Mexico and available at Fiesta and HEB grocery stores. Each cookie has approximately 0.3 grams of fat. They are worth the search.
